El debate en torno a la cuestión del estatuto del embrión humano ha llegado hasta nuestra ciudadanía a través del problema del aborto, en el que detractores y defensores forman dos bandos opuestos y beligerantes, donde el diálogo se ha tornado prácticamente imposible: son las llamadas posturas _pro-life _y_ pro-choice_. Para intentar dar una solución al conflicto, nuestro objetivo será revisar los conceptos de «potencialidad» y «suficiencia constitucional», ambos procedentes de la filosofía, gracias a los cuales pensamos que podrá aclararse (...) la problemática que sobre el estatuto del embrión surge en nuestros días. Una vez revisados ambos conceptos, propondremos una solución a esta cuestión acudiendo a la ciencia, concretamente, a la neonatología y a su concepto de «viabilidad fetal», con el fin de completar una posible argumentación que aporte alguna luz al problema planteado.

El objetivo de este artículo es examinar la postura sobre la cuestión del final de la vida humana en la obra del bioeticista español Diego Gracia. Para ello, primero trataremos el concepto de confín presente en su pensamiento bioético, para pasar después a preguntarnos sobre la determinación que desde la ciencia puede hacerse del momento de la muerte. Posteriormente, nos ocuparemos de la idea que el bioeticista tiene de la muerte desde la filosofía, mostrando las influencias recibidas del pensamiento de (...) su maestro Xavier Zubiri. Concluiremos nuestro artículo con la exposición de algunas consideraciones éticas que de los planteamientos de Gracia se desprenden. (shrink)

Tras la conquista castellana de Córdoba, en 1236, la nueva parroquia de San Nicolás de la Ajerquía aprovechó como iglesia una pequeña mezquita junto al río Guadalquivir. El edificio, ampliado a mitad del siglo XVI y reiteradamente transformado a lo largo del tiempo, mantuvo la preexistencia islámica hasta las importantes reformas del período 1725-27, que supusieron su total demolición. Pese a que existen varias alusiones documentales de aquellos años y un dibujo a mano alzada de la planta conservado en el (...) archivo parroquial, esta mezquita ha pasado prácticamente inadvertida en la historiografía especializada, quizás porque los escasos y ambiguos datos conocidos no permiten estimar su arquitectura. En este trabajo se analiza directamente el dibujo original, contextualizándolo con distintos planos y documentos históricos. Esto ha permitido formular una hipótesis sobre las dimensiones de la sala de oración de la mezquita, su orientación aproximada, así como sobre su conformación arquitectónica interior: una planta prácticamente cuadrada, organizada en nueve ámbitos con cierta autonomía espacial y cubiertos con bóvedas. Seguiría en esto a un tipo de mezquita hace tiempo detectada por Creswell, que la denominó «nine-dome-mosque», y de la que sería el único ejemplo conocido en Córdoba. (shrink)

In this article, we aim to evaluate the role of robots’ personality-driven behavioural patterns on users’ intention to use in an entertainment scenario. Toward such a goal, we designed two personalities: one introverted with an empathic and self-comparative interaction style, and the other extroverted with a provocative and other-comparative interaction style. To evaluate the proposed technology acceptance model, we conducted an experiment (N = 209) at a public venue where users were requested to play a game with the support of (...) the TIAGo robot. Our findings show that the robot personality affects the acceptance model and three relevant drivers: perceived enjoyment, perceived usefulness, and social influence. The extroverted robot was perceived as more useful than the introverted, and participants who interacted with it were faster at solving the game. On the other hand, the introverted robot was perceived as more enjoyable but less useful than the extroverted, and participants who interacted with it made fewer mistakes. Taken together, these findings support the importance of designing proper robot personalities in influencing users’ acceptance, featuring that a given style can elicit a different driver of acceptance.

This study aimed to investigate the student-athletes' capability to face the academic, sport, and social challenges during the coronavirus disease 2019 (COVID-19) lockdown and to disclose novel aspects of dual careers. A 32-item online survey encompassing demographic characteristics, sport and university engagement, support and dual-career benefits, physical activity, sitting time, and the time deemed necessary to recover the previous level of performance was developed. Four hundred sixty-seven student-athletes (males: 57%, females: 43%) from 11 countries, competing in 49 different sports (individual: (...) 63.4%, team: 36.6%) at regional (17.5%), national (43.3%), and international (39.2%) levels, and enrolled at high school (21.9%) and university (78.1%) levels completed the survey. During the lockdown, the respondents decreased the time dedicated to sport and academics, although they maintained an active lifestyle. Student-athletes from countries under severe contagion were more likely to train at home, dedicate to academics, and receive support from the coach but less likely receive support from their teachers. With respect to their team sport counterparts, athletes competing in individual sports trained more and were more likely to receive support from their coaches. International athletes showed the highest training time and support from their coaches and as student-athletes. High school students received more support from their coaches and teachers, whereas university students were more likely considering dual careers useful to cope with the COVID-19 pandemic. This study substantiates the relevant role of competitive sports participation in the maintenance of active lifestyles, with student-athletes considering home training and e-learning valuable resources during the lockdown. Furthermore, their sport and academic commitments helped student-athletes cope with the emergency of the COVID-19 pandemic. (shrink)

The DNA‐passage activity of topoisomerase II accidentally produces DNA knots and interlinks within and between chromatin fibers. Fortunately, these unwanted DNA entanglements are actively removed by some mechanism. Here we present an outline on DNA knot formation and discuss recent studies that have investigated how intracellular DNA knots are removed. First, although topoisomerase II is able to minimize DNA entanglements in vitro to below equilibrium values, it is unclear whether such capacity performs equally in vivo in chromatinized DNA. Second, DNA (...) supercoiling could bias topoisomerase II to untangle the DNA. However, experimental evidence indicates that transcriptional supercoiling of intracellular DNA boosts knot formation. Last, cohesin and condensin could tighten DNA entanglements via DNA loop extrusion (LE) and force their dissolution by topoisomerase II. Recent observations indicate that condensin activity promotes the removal of DNA knots during interphase and mitosis. This activity might facilitate the spatial organization and dynamics of chromatin. (shrink)

A growing number of recreational races are being held in different locations, drawing many local and visiting runners. This study examined the relationships between quality, value, satisfaction, and loyalty among runners in a recreational race and examines potential differences in relationships between these constructs based on the runners’ experience. The participants were 985 runners with a mean age of 40.74±9.41years. Validated, reliable ad hoc instruments were used. A multi-group analysis was performed to ascertain the existence of relationships between the constructs (...) and differences in the relationships between the different study groups. The results show that quality is a direct antecedent of value and satisfaction. Value is directly related to satisfaction and indirectly related to loyalty. Satisfaction is related to the loyalty of participants in the race. Differences in the relationship between satisfaction and loyalty were dependent upon the runners’ experience. Loyalty to a race depends primarily on satisfaction and is modified by the runners’ experience. (shrink)

IntroductionThe prefrontal cortex plays a crucial role in cognition, particularly in executive functions. Cortical reactivity measured with Transcranial Magnetic Stimulation combined with Electroencephalography is altered in pathological conditions, and it may also be a marker of cognitive status in middle-aged adults. In this study, we investigated the associations between cognitive measures and TMS evoked EEG reactivity and explored whether the effects of this relationship were related to neurofilament light chain levels, a marker of neuroaxonal damage.MethodsFifty two healthy middle-aged adults from (...) the Barcelona Brain Health Initiative cohort underwent TMS-EEG, a comprehensive neuropsychological assessment, and a blood test for NfL levels. Global and Local Mean-Field Power, two measures of cortical reactivity, were quantified after left prefrontal cortex stimulation, and cognition was set as the outcome of the regression analysis. The left inferior parietal lobe was used as a control stimulation condition.ResultsLocal reactivity was significantly associated with working memory and reasoning only after L-PFC stimulation. No associations were found between NfL and cognition. These specific associations were independent of the status of neuroaxonal damage indexed by the NfL biomarker and remained after adjusting for age, biological sex, and education.ConclusionOur results demonstrate that TMS evoked EEG reactivity at the L-PFC, but not the L-IPL, is related to the cognitive status of middle-aged individuals and independent of NfL levels, and may become a valuable biomarker of frontal lobe-associated cognitive function.

The introduction of a new analytical method, due fundamentally to François Viète and René Descartes and the later dissemination of their works, resulted in a profound change in the way of thinking and doing mathematics. This change, known as process of algebrization, occurred during the seventeenth and early eighteenth centuries and led to a great transformation in mathematics. Among many other consequences, this process gave rise to the treatment of the results in the classic treatises with the new analytical method, (...) which allowed new visions of such treatises and the obtaining of new results. Among those treatises is the Arithmetic of Diophantus of Alexandria which was written, using the new algebraic language, by the French mathematician Jacques Ozanam, who in addition to profusely increasing the original problems of Diophantus, solved them in a general way, thus obtaining many geometric consequences. The work is handwritten, it has never been published, it has been lost for almost 300 years, and the known references show its importance. We will show that Ozanam’s manuscript was quoted as an important work on several occasions by others mathematicians of the time, among whom G. W. Leibniz stands out. Once the manuscript has been located, our aim in this article is to show and analyze this work of Ozanam, its content, its notation and its structure and how, through the new algebraic method, he not only solved and expanded the questions proposed by Diophantus, but also introduced a connection between the algebraic solutions and what he called geometric determinations by obtaining loci from the solutions.

This article examines the relationships between gender and technology in Spanish feminist praxis online and argues that different perspectives on online feminist community-building offer distinct responses to cyberactivism, which is considered central to sustaining efforts for social change. To ascertain whether Spanish virtual communities and cyberactivism have the potential to address the challenges posed by the relations between gender and technology, we analyse feminist scholar Remedios Zafra's theoretical proposals, and the different ways in which this theory intersects with the cyberactivism (...) put forth by two feminist web portals, Ciudad de Mujeres and Mujeres en Red. We will discuss to what degree particular Spanish feminist theory and practice online adapts to or challenges utopianism regarding the liberating potential of technology. We will also examine how, in the face of critical arguments about such liberatory possibilities, two options present themselves for women's effective use of technology: inhabiting or occupying the web through the construction of feminist communities online.

Since the 1990s, the reality television phenomenon has transformed the face of television in many countries. In Spain, for instance, the private domain has gradually invaded the public domain in an attempt to increase audience ratings and also reflect patterns of asymmetrical societal organization. Different television formats, which range from docusoaps to the most blatant examples of so-called ‘voyeur television’, have occupied the prime-time hours. In particular, a wide range of reality television shows has taken the place that mini-series, sitcoms (...) and films of the week used to occupy. These reality television programmes show the transformation of the private domain into one which can be manipulated and incorporated as an essential element in the theatricalization of the intimate experiences of anonymous people. By addressing the relationship between mothering and gendered styles, this study adds to the field of research on reality television research by investigating language and gender within the institutional setting of a docusoap and throwing light on the discursive strategies which two different generations of women use to express anger and assertiveness and impose on others. The study reveals that the strategies used by the Spanish female teenagers under scrutiny are associated with hostile laddish verbal behaviour, whereas the mothers’ strategies relate to an instrumental view of aggression.

Citizen science is growing quickly, given its potential to enhance knowledge coproduction by diverse participants, generating large and global data sets. However, uneven participation in CS is still an important concern. This work aims to understand participation dynamics in CS and how they are shaped by participation barriers and drivers. We do so by examining participation in CONECT-e, a CS project that uses a wiki-like platform to document traditional ecological knowledge. More precisely, we analyze quantitative data on participants’ profile and (...) activity patterns and qualitative data on barriers and drivers of participation. Our findings suggest that overcoming the education, age, and residence participation barriers is challenging even in cocreated CS projects. This is potentially due to issues of perceived self-illegitimacy and low access to information and communication technologies. Our results also point out that participants’ alliance with the project’s objectives and trust relationships with the project team are important drivers of participation in CS projects. Finally, we also highlight the need to think beyond participation as single actions and rather consider participation diversity in CS as functional diversity in ecosystems, with participants performing a diverse set of interconnected tasks or functions.

«Aristotle in Spain in sixteenth century. Background, significance and aspects of his influence». The aim of this paper is to explain, on the basis of some significant testimonies, the way in which Aristotelianism penetrates in Spain, and how this penetration of the new Aristotelian thought in the European countries reveals a permanent conflict between the Middle Age and the Renaissance, particularly in Spain, where the rediscovery and the use of the ancient authorities very often constitutes an important theoretical problem. The (...) author shows some of these difficulties with examples from many fields. (shrink)

Este texto analiza el modelo de masculinidad transferido por las narrativas icónicas de los libros de texto de Ciencias Sociales de 5º de E. Primaria. Partiendo de la coeducación como herramienta transformadora de los patrones masculinos hegemónicos tradicionales asociados a la agresividad, la competitividad y la violencia, se abordan los estudios de género sobre la historia escolar, a fin de realizar un diagnóstico sobre la situación actual en torno a las investigaciones de las masculinidades en la Didáctica de las Ciencias (...) Sociales. Se ha creado una ficha multivariable, fácil y sencilla, a fin de que pueda ser aplicada por el propio alumnado de Primaria en sus propios libros de texto, los cuales pasan de ser instrumentos transcriptores de relatos históricos construidos, a ser herramientas de discusión y reflexión crítica sobre género en el pasado y el presente.

The point of departure of this article is the distinction established by Giuseppe Duso between governo and potere , between the old politics focused on the forms of government and the modern politics based on sovereignty and legitimate representation. Contemporary liberal democracies fundamentally coincide with semiotic representation, which, if we agree with Ackerman, makes its first major appearance with the North American Federalists. However, we consider that authentic democracy is that which is rarer, to be found beyond government and power, (...) where the nobodies, those who do not need any titles in order to participate in the public sphere, question –as Rancière explains– the continuity between the natural or social order and the constitutional or political order.

Neste artigo pretende-se discutir a dimensão política presente na origem da teoria do reconhecimento de Axel Honneth, partindo da constatação de que durante a reelaboração de sua tese de habilitação, publicada em 1992 com o título de Luta por reconhecimento, o autor se posiciona pela primeira vez diante do debate entre liberais e comunitaristas e elabora seu conceito formal de eticidade como uma resposta às limitações de cada uma dessas correntes da teoria política contemporânea.

Empirical research on the effect of religion on attitudes toward the environment remains divided into two opposing points of view, which claim a positive or negative effect on pro-environmental attitudes. This study analyses these relationships in a Spanish sample from a multidimensional perspective. The results of this study show, this time in a European context, the negative relationship between religious literalism and concern for the environment previously found in studies based on American samples. They also show the negative influence of (...) specific aspects of expressions of Judaeo-Christian religiosity, especially the rigidity characteristic of some non-traditional dimensions of religiosity, which arguably can be present without the co-presence of biblical literalism, and also the positive effect of quest-oriented religiosity and approaches focusing on existential well-being. The unique contributions of these variables in explaining concern for the environment are mapped to specific variances in the outcome variables. (shrink)
